My Little Sister Can Read Kanji: Volume 4

Gin's summer is just beginning, and his family and all his little sisters (even old men that just take the form of little sisters) head to the beach for a little fun, which can only mean one thing: Literary Experiences galore! But Gin is still processing what happened that night in Kuroha's room… Something is changing in him and his relationship with Kuroha… And greater forces are beginning to make themselves felt from the shadows.
